How to use alias name in where clause

Hello,
DECODE (item.inv_type,'OT', (DECODE (item.attribute2, 'STONE', 0, xfer.release_quantity1 * xfer.attribute10)
'FG', (xfer.release_quantity1 * xfer.attribute10)
) matl_val
In the above code matl_val is alias name i need to use that one in where clause as
where matl_val > 0
is this possible or anyother way can anyone help me.

But the point is as you haven't read the documentation you may miss some valuable points about alias and will soon end with another problem.
>
Specify an alias for the column expression. Oracle Database will use this alias in the column heading of the result set. The AS keyword is optional. The alias effectively renames the select list item for the duration of the query. The alias can be used in the order_by_clause but not other clauses in the query.

I did not understand your query but have you tried using the HAVING clause?
HAVING clause allows you to use a "where" like condition for your groupings.
See http://www.techonthenet.com/sql/having.php for some examples.

How to use CASE stmt in Where clause

How to use CASE stmt in WHERE clause?. I need the code. Please send me as early as possible..........

Hi,
How to use CASE stmt in WHERE clause?. There's no difference between how a CASE expression is used in a WHERE clause, and how it is used in any other clause. CASE ... END always returns a single scalar value, and it can be used almost anywere a single scalar expression (such as a column, a literal, a single-row function, a + operation, ...) can be used.
CASE expressions aren't needed in WHERE clauses very much. The reason CASE expressions are so useful is that they allow you to do IF-THEN-ELSE logic anywhere in SQL. The WHERE clause already allows you to do IF-THEN-ELSE logic, usually in a more convenient way.
I need the code.So do the peple who want t help you. Post a query where you'd like to use a CASE expression in the WHERE clause. Post CREATE TABLE and INSERT statements for any tables used unless they are commonly available, such as scott.emp). Also, post the results you want from that sample data, and explain how you get those resuts from that data.
See the forum FAQ {message:id=9360002}

You can use a timestamp literal, or use a function that return a timestamp datatype, here is an example:

select * from yourtable where column2 between TIMESTAMP '1997-01-31 09:26:50.12' and systimestampHave a look to the documentation, for example http://download.oracle.com/docs/cd/B19306_01/server.102/b14225/ch4datetime.htm

How to use Alias name in OData service in SAP HANA

Hi,
     I need to change one column name with alias of another name in odata service definition or odata url running in rest client. I am trying to give alias name with as key in the service definition like sql query.
ex:
There is one table with column name of PRODUCT_ID. I exporting that table via odata service to SAP UI. In the UI i dont want the product id column as PRODUCT_ID. It should be ike "Prodcut". Like we are using in SQL example
select "PRODUCT_ID" as "Product" from "producttab";
But i can't use as key for alias name. So i am getting syntax error.
I have tried in rest client also ie executing odata file in rest based service. But i got error only.
If anyone knows about this alias name in odata service, Please help me to resolve this issue..

Hi Thomas
     Thanks for your reply.
     Actually in odata service definition i am using attribute and calculation views only. But in some case from the model view itself i need to use some alias names to the UI through odata service.
     For example in attribute view i have some columns with name col1,col2... I am getting those columns in UI using odata service, for particular col2 column i need to change column name as product. And i am using the same view as source of another odata service in that service i need to change that column name as productname.
     In that case i need alias name usage. So that only i am searching alias keyword in odata service.
     Is there any possibility to use alias names in odata service.

select ...

where to_number(to_char(date_column,'MM')) Between 9 And 10;You could also do something like:
select ...

Both operands to LIKE are supposed to be strings. Don't try to use a DATE, such as SYSDATE, with LIKE.

SELECT ITEM_NAME, available_date FROM TEMP WHERE available_date >= SYSDATE ;
It's returning the results I expect.
If you'd say what results you were expecting, someone could help you wite a query to get them.
Assuming 1 second elapses between the time 'ITEM4' is inserted and the time the 2nd query is run, then, at run-time, available_date will be 1 second less than SYSDATE, so it should not be included.
If you want to find rows that are on the same calendar day as SYSDATE, or later, then use
WHERE available_date >= TRUNC (SYSDATE)

How to use division with a Where() clause

I have to report four specific time periods dynamically so I made Date variables. I cannot use division of the metrics without applying the date codes to the individual metrics. There has to be a way I am not thinking of. This is a massive report so I need to keep variables to a minimum.
Example:
[Sales 1] / [Quota 1] = Percent to Quota
I have a Date Variable for Quarter to Date: [Months in QTD] That returns multiple "Fiscal Periods" (months) per date formulas
However, to get the right time period data using DIVISION, say for Quarter To Date I have to use:
[Sales 1] Where( [Fiscal Period] = [Months In QTD]) / [Quota 1] Where( [Fiscal Period] = [Months In QTD])
The above returns the correct value for the three months in the quarter.
That would be OK except I need an IF..Then..ElseIf..Else statement to solve for zeros and nulls and it gets very long adding the “Where( [Fiscal Period] = [Months In QTD])” to every measure in the statement.
I have tried nesting: =(SUM( [Sales 1] ) / Sum( [Quota 1) ) Where( [Fiscal Period] = [Months In QTD])
And that does not work as with other attempts to nest.
I tried an IF( [Fiscal Period] = [Months In QTD] … but it returns MULTI error I assume becaause the variable [Months in QTD] delivers more that one Fiscal Period.
Come on brainac’s. Division has its own rules but there should be a way.
Thank you.

Hi,
Just to give you rough idea. I would suggest you to apply following logic at query level.
Create a query with prompt and try to get Months in QTD there only a single object.
Now apply filter on second query "where result from another query" that will filter data for perticular quarter.
I hope you can understand.
Thanks,
Swapnil

How to Concatenate Table name and Where condition at runtime

I am passing parameter as User and Zone to Stored Procedure.How to concatenate Table Name
and WHERE CONDITION in SQL Statement.i have different type of users and zones.

Hi !
declare
cur sys_refcursor;
r emp%rowtype;
v_sql varchar2(512);
begin
-- do your logic here
v_sql := 'select * from emp';
open cur for v_sql;
loop
    fetch cur into r;
    exit when cur%notfound;
    dbms_output.put_line(r.ename);
end loop;
close cur;
end;In this example you can see how can be done this with cursor vars .. You should concatenate v_sql string according to your requirements.
But as in further posts has already been mentioned , be carefull at publishing such kind of procedures and think on security.
Also when you want dynamicaly change from clause , you should consider using different records to accept data ? Maybe all your tables has the same structure and then this problem will be smaller.

Using alias name from view

Can I create somehow a view like this one:
CREATE VIEW clerk_view AS
   SELECT employee_id as ei, last_name as ln, department_id as di
   FROM employees
   WHERE job_id = 'PU_CLERK' ;and using this view with aliases, e.g.:
select * from clerk_view where ln = 'Mickey';
My Oracle database version is 11.2.0.3
Best.

Hi,
lesak wrote:
So can you tell me what I'm missing in above CREATE statement? Sorry, no, not without knowing exactly what you're doing. That's why you need to post a complete test script that people can run to re-create the problem. Except for the identifier LN, there's nothing wrong with the code you posted per se , but there could be millions of things wrong with how how you're trying to use it. Even if I could post millions of suggestions, you wouldn';t want to read them all, just to fond the one or two that apply to your case. So way exactly what your case is. Post a complete test script that creates and populates the table (if necessay), calls the view, tries to use the view, and gets the error.
When I create view in the same way in production and use alias name, I've got following error: ORA-00904. Not everyone who wants to help you has all the error codes memorized. That's why you should post the complete error message.
So Oracle don't know that my employee_id or other column have also alias name?!Sure, it will know the alias name. That's exactly what aliases are for.

How to specify alias name in system property while making 2way SSL con ?

Hi All,
I am tring to run a java client with 2way SSL which uses CAC card as keystore for the client. I have addded the following system property in my client program to make it work and change the java.security file to add pcks11 provider.
System.setProperty("javax.net.ssl.keyStoreType", "pkcs11");
System.setProperty("javax.net.debug", "ssl");
The program works fine and handshake is successfully done . But the problem is when i have more than one trusted certificate in the CAC card, it take a default certificate. I want to specify the certificate that should be used to do the client auth maybe specify the alias name . I didnt find any system property to do so.
Please let me know how to specify alias name as system property so that the 2way SSL used the specified alias for the client auth or is there any other way to specify the alias name. As in case i acccess the server URL from any browser i get a certificate selection prompt and the connection is established with the selected certificate.
Thanks in advanced,
Ruhul

I didn't find any system property to do so.There isn't one.
Please let me know how to specify alias name as system propertyYou can't.
You would have to write a custom KeyManager. See the JSSE Reference Guide.
